58 // The DeclExpr class serves as a tag for all expression templates that represent an explicit
59 // declaration operation. All classes, that represent a declaration operation and that are used
60 // within the expression template environment of the Blaze library have to derive publicly from
61 // this class in order to qualify as declaration expression template. Only in case a class is
62 // derived publicly from the DeclExpr base class, the IsDeclExpr type trait recognizes the class
63 // as valid declaration expression template.
